S01E21 — Miracle

The Pure Place is enshrouded with flames and with bitter cold as the battle between Reishin and the Masagami begins. Kuro awakens from her stasis soon after Keita does, and is shortly suppressed of her inner Masagami. She and Keita now know that Reishin was not the one to really slaughter his own clan and has done all he has done up to this point in order to protect Kuro from awakening as one of the Masagami and contributing to the destruction of the world. Reishin is pounded by attacks of magma and glaciers, but with the aid of the Thousand Iolite Abyss, he unleashes the powered-up Exceed Tera Cannon to destroy the body of the two Masagami. With his last-founded attack, he uses up all his Tera and dies while impeding the Masagami's ability to regenerate.
